<p>A tool (10) is provided for radially expanding a downhole tubular (C), and includes a central tool mandrel (12), a tubular expander (48) at the lower end of the tubular, and a downhole actuator (15) for forcibly moving the expander axially within the downhole tubular. Slips (20) are positioned for securing the tool within a well, so that the slips may be set, and the tool subsequently stroked to move the expander (48) and radially expand a length of the tubular. Upward pull on the work string may expand long portions of the downhole tubular. Buttress threads (43) preferably support the tubular expander on the downhole tubular when run in the well.</p> |
